According to the announcement McLaren will in conjunction with BMW develop “new combustion technology that will deliver a higher output per capacity than currently possible” for its next-generation supercars and hypercars.
“It also aims to further facilitate CO2 reductions while simultaneously increasing engine output [and] is destined for application in future McLaren engines,” the brand added in a statement.
The current 675LT’s 497kW 3.8-litre twin-turbo V8 M838T engine makes a specific output of 130kW per litre that will be trumped by the new engine.
BMW has not yet made an official statement about the venture, although it will sell its engine technology to McLaren rather than co-produce an engine to be shared across different model lines.
“We will continue to independently design and build our own engines,” confirmed McLaren Automotive CEO Mike Flewitt.
“This is an exciting project that plays to the strengths of all partners … and the benefits of this project will help us accelerate the development of our next-generation powertrain, as confirmed in our recently-announced Track22 business plan.”
McLaren has gained part-funding from the UK government for its new engines, and will continue working with existing engine manufacturing partner Ricardo, lightweight casting producer Grainger and Worrall, and composite structure specialist Lentus Composites.
It is unclear when the new technology will arrive, but given the early-2017 announcement it could be a number of years before the new drivetrains are set for production.
The Track22 plan will begin at the Geneva motor show on March 7 when the McLaren P14 (or 720S) makes its debut as the next-generation flagship supercar. Another 15 new cars are set to arrive before 2022 – many of which will no doubt feature BMW technology.
